Hi,

Thanks for your answer. I see now where the problem comes from, but your  
“trick” is apparently not sufficient. The code…

class Garden \< ActiveRecord::Base  
include DRbUndumped  
has\_many :flowers  
alias :id\_\_ :id  
end

class Flower \< ActiveRecord::Base  
include DRbUndumped  
belongs\_to :garden  
alias :id\_\_ :id  
End

… Still does not work…

Hey Philip-

```
I have dealt alot with ActiveRecord over drb, I use it in this

```

plugin for rails[1] . The way around this is to use a different  
notation to get the id of the AR object. So with your client example  
change it to this and you will be fine:

#!/usr/local/bin/ruby  
require ‘drb’

DRb.start\_service()  
obj = DRbObject.new(nil, ‘druby://localhost:9000’)

g = obj.find(1)  
puts “#{g[:id]} | #{g.name}”  
g.flowers.each do |f|  
puts “#{f[:if]} | #{f[:id]} | #{f.name}”  
end

```
So by using arinstance[:id] instead of arinstance.id you will avoid

```

this problem all together.
